a llangige 04,01 a. band cs whieli'is fixed on the folly c'l oi thewheel. The riin is-A adapted to hereniox'aliilyseeiired on the wheelliti-"bolts c which are secured in felly and liigs which fit in thespace between the inner fiie ot the rim a. and the outer face orperiphery of band es and are, formed with portions d2' for engaging oneof the lianges a of the rim. the lugs, being held hy niits d3.

lThe ends of side-flanges b of filler-section 71 are convergent orinclined aszit b and the ends ot side-flanges 1l of the niain lstrip aare. correspondingly inclined or eon i-'ergent-g as :it n, so that ihese flanges of section b 'will spread or ii'edgethe rini ends 70 apartas the iiller-sectioii is forced'between the ends olf the flanges a. tocanse the fillerseetion to tit snugly between the. riin" ends.. .liymeans ot these inclined ends, @spreading tool for separating the.riinfend's'to receive' 75 the filler-section may.' in most eases, 'bedis-l pensed with, and the removal "f the filler` section will hefacilitated.. A'iplate ellis se ciiied to the inner. face offiller-section b. by' 'I rivets e and is adapted to lit inthespace'bel80 tween the inner fece of the riin'aiid the outer :face orperiphery of band c3. `This platev provides a tirin bearing 0n the bandfor the filler-section, and projects longitudinally from the. ends ot'the filler-section, as at e 85 to Aunderlie the. riin-ends.

For the purpose offhicking the lfille-' 'section in plaine hetween theends'oftheinain'V sirip and for forcing it outwardly between sa id ends,a screw f is secured or `Awelded in the oase et' each of die ends of theinain strip a. and these extend inwardly Afrom the hase, of the. i'iiii.'lach of these screws is' adapted to extend through a slot e2 in oneendof `plate 1.?. llaeh slot is elongated longitiidinalli' of 'the iiinto permit separation of the bolts i by section 2'?, and niits f areadapted to rainp the projectingr ends e5 of plate. i' :iL-:ip t theinner lfaee o the ends of strip fr. .Niiler-seiftioii (i isprovidcd withan opening L Vfor the tire. valve. The projectnig ,-iids of plaie e areformed with recesses c*"`\..hieh are adapted to reeeii'e'tongnes g* onplates y whir-h are riveted, as at Q?Qto the inner time of the ends otthe innini'iin strip 105.

serie i'oseeiire the {illenseetioii 7) with its 1104 disposed andprevents the rim .from being bent inwardly at these points.

The wheel-band c and telly c2 are cut away, as at c5, to form recessesfor receiving the nuts f. and a hole c extends through seid band andfelly for the tire-valve. Nuts f are provided with flanges f2 which titsnugly in the hole c5. in the band.

To place a tire on the rim, one end of the main. strip a will be placedon the inner portion of the tiro and the other end may be sprunginwardly and 'contracted and then i shifted into place on the tire sothat. the

of the tire will rest in the channel of ti e rim, and the filler-sectionb will then be i in the gap between the ends of the main strip, screwsf.being passed through main holes e2 in plate e. Nuts f will then betightened, the illenseetion will be forced into the ga between therim-ends and the latter will i e wedged apart by the inclined edges ofthe side flanges b. As the nuts f are tightened, lslots e2 will permitthe screws to spread with the rim ends, and tongues g will pass into therecesses e* on the plate e. `When the nuts have been tightened to firmlysecure plate e against the inner face of the strip the surfaces formingthe rim channel` will be flush, the filler-section will be locked inplace and the interlock between the ends of plate e and lugs g willsecure the filler-piece andfthe, ends of the 'strip a against relativelateral and radial move-A ment. Th'e'frim with the tire thereon maysafely be carried Without danger of loss of the filler-piece.' Vlhen therim with the tire thereon is to be placed on the wheel, it 'is' onlynecessary to place the rim in snch ange;- lar relation to the wheel`that nuts fzrwill into recesses and the rim may tlen be forcedlaterallyl fin-the wheel and secured thereon by lugs Vand nuts al-,Vhenthe tire is to be removed from the ridi, thejlatter will lirstvberemoved from the wheei. then nuts f will be loosened, llensection e willbe removed so that the ends oi"- the main strip a may be sprung inwardlyand laterallvof the tire to separatethe rim from the tire.

The invention A thus exemplifies an iniproved demountable rim in whichthe tillen piece or section is provided with inclined in tegral flangesfor spreading the ends of the main n to e'ect a snug fit' between thecontigs ed of the filler-section and the ends the main strip; also onein which 'the filler t: n will be rigidi)r secured in place i ,h isrigid thereon and extends aci e gap between the rim ends and which can ligidly secured to the inain strip inde ,ntlv of the tire, so that whenthe rim fried without a tire thereon, it f firmly held in place; andwhich this rigid plate is interthe ends of the .main strip to i iat-ivelateral movement of the v lon and the main strip.

The invention is notto be understood :is restricted to the details setforth, since these may be modilied within the scope of the appendedclaims, without departing from the spirit and scope of the invention.

Having thus described the invention, what.

I claim as new and desire to secure by Letters Patent, is:

l. A demonntable tire rim comprising the ,cmlflinnion of a main striphaving a gap between its ends so that said ends may be flexed, aremovable one-piece rim section litt-ing in and filling the spacebetween said ends, the ends of the mainstrip and the filler-sectionbeing correspondingly tapered so that the filler-section will spread andfit snugl;7 between the ends of the main strip when forced therebetween,and means secured to the ends of said main strip and engagging saidfiller-section for forcing the latter to position in said rim.

A demountalile tire rim comprising the combination of a main striphaving integral side fianges for engaging and holding a tire and havinga gap between its ends so that ingl'y tapered so that the filler-sectionwill .1'.

spread the ends of the main strip when forced therebetween, screw boltson the riniends for detachably securing the filler-section to the mainstrip, and means for removably securing the rim on the body.

3. A. demountable tire rim comprising the combinatien of a main striphaving' integral side flanges for holding a tire and a gap between itsends so that they may be flexed, a one-piece rirn-sectien 'w :h integralside flanges for holding,.tlie tire, fitting and filling the spacebetween said ends, the ends of the langes on the main strip. and thelier-section being correspondingly tapered so that the flllerlsectionwill spreadfgth ends ofthe main strip when'forced therebetween, a platerigidly secured to the inner face of the filler-section, and screw boltson the ends the illensection to the main strip.
